Atrophic gastritis can lead to intestinal dysfunction. Causes of dysfunction include reduction of gastric juice, mental factors and so on. 1. Reduced gastric juice: gastric juice can stimulate intestinal peristalsis, atrophic gastritis leads to a reduction in gastric juice, which in turn leads to a decrease in gastrointestinal peristalsis and intestinal dysfunction. 2. Mental factors: long-term atrophic gastritis can lead to long-term mental anxiety. Adverse emotions through the cerebral cortex lead to hypothalamic dysfunction, which affects the function of the gastrointestinal tract. Intestinal dysfunction, also known as intestinal neurosis, is a group of intestinal syndrome, mainly manifested as intestinal motility and secretion dysfunction. If you are suffering from atrophic gastritis with intestinal dysfunction, you should go to the hospital in time and take active treatment.
